Mercury Mariner Reviews

I bought my Mariner in 2011 with 83k miles its a good vehicle with best quality ever. My last car was a 1995 Toyota Camry that I've purchased new but sadly totaled my vehicle an very reliable car ever too but needed another dependable ride. Overall love my Mariner its nice runs and drives like a champ, there no issues with nothing good car has good handling with the V6 and the performance is be...
Had the mariner for 7 months now and I am really pleased with it. The V6 has plenty of pep for me and I really like the 30+ miles per gallon. I like the visibility and the head room. Tried a chevy equanaux and could not get in without bumping my head. I had a 03 mariner and it was about the same but not as good gas mileage. I think I will stick with mariners.
2008 Mercury Mariner - I have had my car for 6 years, over 108,000 miles and have never had a single problem with it. It still rides great. I have never had to have the breaks replaced, not even the battery. Nothing leaks and the Sewell Ford dealership in Odessa, TX has the best service of any dealership I have ever used. They are the very best.
